medius. Among the Mustelida) the muscle is very constant, being 

 inserted into the first and second digits in Galictis vittala ((53), 

 Mustela jmtorius (65), M. foina (66), Ictony.v zoriUa (69), /. libijca 

 (70), Mdes (71), Lutra vulgaris (74, 76), and L. cinerea (78). In 

 Haiighton's specimen of L. vulcjaris (79) the insertion was into the 

 second and thii-d digits. 



Muscles of the Hand. 



Flexor hrevis digitonim manus. — When this muscle is present 

 in the Carnivora it rises from the annular ligament, pisiform bone, 

 and palmar fascia, and occasionally from the lower part of the 

 palmaris longus tendon. It is inserted into the vaginal sheath of 

 the minimus, or, if it is more fully developed, forms the flexor 

 perforatus of that digit. Among the Felidaj the muscle was

present in F. Ico (1 a), and apparently in Macalister's specimens of 

 Felis lea (1) and F.pardus (4), though in these it went to the fourth 

 and fifth digits. In the Yiverrid* it was present and formed the 

 flexor perforatus tendon to the minimus in Viverra civetia (12), 

 Herpestes (24) (see fig. 10), and Geneita (17). In V. civdta (14) and 

 Genetta (18) it ended in the vaginal sheath, and, in the latter animal, 

 went to the fourth and fifth digits (see fig. 9, p. 396). Among the 

 Hyaenidse it was present in Hijcena crocuta (29), but not in B. striata 

 (26, 28). We have no records of it among the Canidae or Ursidae, and 

 it was certainly absent in our sj^ecimen of Cam's familiaris (31). In 

 the Procyonidae it seems very constant ; it is px'eseut in Procyon lotor
